SHOCK-ABSORBER.

Application filed May 28, 1914;. Serial No. 841,424.

To all whom it may concern Be it known that I, ARTHUR A. BARBER, asubject of the King of England, residing at Detroit, in the county ofWayne and State of Michigan, have invented certain new and usefulImprovements in Shock-Absorbers,

of which the following is a specification, reference. being had thereinto the accompanying drawings.

This-invention relates to shock absorbers,

.and the primary object of my invention is to provide a simple, durableand inexpensive hydraulic shock absorber that can be advantageously usedin connection with vehicles,

as automobiles, for cushioning one part of the automobile relative toanother.

A further object of my invention is to provide a shock absorbing devicethat can be used in connection with two movable supports or with astationa y support and one movable support, the device includingconnections that permit of self adjustment whereby the device canmaintain itself in proper relation to its support.

The above and other objects are attained by a mechanicalconstructionthat will be hereinafter specifically described and then claimed, andreference will now be had to the drawing, wherei1i- Figure 1 is avertical sectional view of the shock absorber and Fig. 2 is a sideelevation of the same partly in section.

In the drawing, 1 and 2 denote, by th way of an example, the upper andlower members of an elliptic spring commonly used for cushioning oryieldably supporting the body of a vehicle. I

Secured to theupper and lower members 1 and 2 are vertically aliningclamps 3 provided with brackets 4 constituting the socket members ofuniversal joints or connections. The upper bracket 4 is carried by thetop of the clamp secured to the member 1 and the lower bracket iscarried by the bottom of the clamp secured to the member 2, saidbrackets having sockets -5 and sectional glands or retaining rings 6 forthe ball members 7 of the joints or connections.

The lower ball member 7 is carried by the bottom of a cup-shapedcvlinder holder 8, said holder having the wall thereof slotted orslitted, as at 9, and provided with apertured lugs 10 connected by abolt 11 and a nut 12 or other fastening means, whereby the walls of thecylinder holder can be clamped against a cylinder 13 placed withinSpecification of Letters Patent.

Patented Dec. is, rare.

said holder. The cylinder 13 has a detachable bottom plate or plug 14and a detachable cap 15, said cap having a conventional form of stufiingbox 16 for a tubular or hollow piston rod 17. The tubular or hollow 7piston rod 17 is reciprocal longitudinally of the cylinder 13 and theinner end thereof is provided with a piston head 18 having a concentricopening 19 in communication with the bore of the tubular or hollowpiston rod 17. The piston head 18 has packing rings of the ordinary andwell known type adapted to engage the walls of the cyl inder 13.

The outer or upper end of'the tubular piston rod 17 is suitablyconnected, as at 20 to a reservoir 21 that has the top thereof providedwith the upper ball member 7 of the universal joint or connection. Thereservoir 21 has a filling opening 22 normally closed by a detachableplug or cap 23, which permits of oil or a suitable fluid being placed inthe reservoir to flow back and forth through the tubular piston rod 17,when the reservoir :21 moves relative to the cylinder 13 or vice verse.I

The confronting ends of the cylinder 13 and the reservoir 21 areconnected by a detachable apron or flexible inclosure 24, said apronpreventing dirt and other matter from interfering with the reciprocalaction of the piston rod 17.

-It s through the medium of the universal joints or connections that thedevice can adjust itself to receive the thrust of either of the members1 and 2 and cushion a movement of said members. Assuming that the member2 is stationary and the member 1 is shiftedto'ward the member 2 bypressure or a load upon the member 1, the fluid within the cylinder 13must flow through the tubular piston rod 17 and the size of the bore ofthis piston rod determines the cushioning action of the shock absorber.The adjustment in connection with the cylinder holder permits of thedevice being correctly adjusted between two bodies to cushion onerelatively to the other, and while, in the drawing there is illustrateda preferred embodiment of my invention, it is to be understood that thestructural elements are susceptible to such changes, in the size, shapeand manner of assemblage, as fall within the scope of the appendedclaims.

at 15 claim is: 1. The combination with supports, of uni versal' jointsforming part thereof, a cylinder holder forming part of one of saidjoints,;a cylinder adjustaloly supported by said holder, a reservoirforming part of the other of said joint and adapted to receive a fluid,apiston head reciprocal in said cyltubular-piston rod connected to saidhead" and said reservoir and establishing com'- inunication between saidcylinder and said reservoir, and an apron connecting the com frontingends of said cylinder and said reservoir-and inclosing said piston rod.

3. The combination with supports, of

' clamps secured thereto, brackets carried by said clamps, a cylinderholder movably supported by one if said brackets, a cylinder adjustablymounted in said holder, a reser- I voir iovaloly supported by the otherof said brackets and adapted to receiye a fluid, a piston headreciprocal in said cylinder, and a tubular piston rod connected to saidpiston head and said reservoir and establishing communication betweensaid "cylinder and said reservoir.

, 4. The combination with supports, of clamps secured thereto, bracketscarried by said cla1nps,a cylinder holder Inovably supported by one ofsaid brackets, a cylinder adyistably mounted in said holder, a reservoirmovahly supported by the other of said brackets and adapted to receive aflu1d,a piston head reciprocal in said cylinder, a

, tubular piston rod connected to said Piston head and said reservoirand establishing communication between said cylinder and H I said.reservoir, and an apron connecting said.

cylinder and said reservoir.

in testimony whereof I atlix my signature in presence of two witnesses.
